1) What legal risks are you taking on in providing this service, and how will you offset them? Providing the wrong information (two people with the same name, user input error you didn't validate, analytics calculation error, etc.), downtime at a critical moment, client or other confidentiality issues, etc.

2) Where do you get the data from, and how scalable are those sources (e.g. does it vary by municipality)?

Just want to echo others saying it's great to hear how many customer interviews you've done.
